A person who goes into a chat room and gets totally pissed off at someone and takes over their name. The cloner then makes nasty remarks about other chatters creating total havoc in the room. Everyone then iggys the original chatter and the clone. The cloner then takes over someone elses name and does the same thing. Everyone in the room soon hates everybody else in the room. It is hysterical.

Discovered by Dr. Steve Forrest in 2011 while observing a film on human sexual intercourse. A cloner occurs during arousal, when the clitoris of a woman fills with blood causing it to become erect and protrude outward from the vagina.

This often resembles the male "boner" which happens during male arousal when blood fills the shaft of the penis causing it to become hard and stick up in an erect state.
A "cloner" gets its name from combining "clit" which is short for "clitoris"(the piece of skin in a female vagina that contains a tremendous amount of nerve endings that cause great pleasure when stimulated) and "boner" referring to an erect male penis.

A "cloner" will pulsate and become increasingly lubricated from vaginal fluid released during sexual arousal.
Some females have very large "cloners" while others may not have a very noticeable one at all. Sizes range from under an inch to 3" or more.

"I was about to hookup with this girl last night, but right as I was about to go down on her, right where her clit was there was a little nub sticking up!?"
"Dude, your girl has a cloner! Its when her clit gets all hard like a dick! Good thing you didn't eat her out!"
"Yea...about that..."
